Patented Apr. 14, 1931 UNITED STATES PATENT ol-FICE i WTLLIAM H. HEFFERNAN, 0F NORTH ADAMS, MASSACHUSETTS, ASSIGNOR TO 'HEFFER- NAN BRUSH CGMPANY, INC., 0F NORTH Adilv, MASSACHUSETTS, CORPORATION OF MASSACHUSETTS Application led May 10, 1930. Serial No. 451,328.

This invention relates to improvements in coinber rolls for combing raw cotton.

An object of the invention is to provide means for attaching these rolls to the driving shaft. At the present time, diiiiculty is experienced in securing the shaft to the roll since the rolls which are made of layers of paper do not furnish suicient strength for securing a shaft thereto. Broadly, the invention comprises a paper tube which i-s formed with two semi-circular cylindrical portions, the ends of which are reduced in diameter' and 'formed with radial kerfs in the reduced part. Semi-circular cap pieces are iitted onto the reduced portions. These cap pieces are formed with ribs which enter the lerfs or grooves. A collar is located or placed outside of the two semi-cylindrical cap pieces or members. The collar is formed with threaded openings for receiving set screws that are forced against the semi-circular members, thus moving them tightly or iirmiy against the reduced ends of the semicircular cylindrical members, whereby these members are firmly clamped together and to the coliar. r

As a modiiication, the cylindrical members are formed with openings for receiving pins that enter openings in a bearing inember which bearing member closely iits the opening in the tube. The ends of the bearing member are reduced in diameter for seating in the bearing blocksof the machine, as will be described.

Referring to the drawings Fig. l is a perspective View of the two halves of the cylindrical member and showing the cap pieces and clamping collar in place.

Fig. 2 is a detail sectional view showing the manner of securing the bristles to the layers of paper composing the cylindrical member.

Fig. 3 is a perspective view of the cylindrical member illustrating one of the reduced ends and the radial lrer'fs therein.

Fig. 4 is a separated view of the cap pieces which engage the reduced ends of the paper cylinder.

Fig. 5 is a perspective view of the clampingcollar which engages the cap pieces, and

Fig. 6 isa modification showing the .pin means for securing the bearings to the layers .of paper comprising the paper tube.

Referring to the drawings in detail:

`1` and 2 designate the two semicylindrical members, composed of paper which `form the cylindrical tubular member, the layers .of which are indicated at 3. The ends of. the cylinder, only one oi' whichis showinare reduced `in diameter, as indicated by thenumeral 4. 5 and 6 indicate redial kerfs or grooves. that are cut inthe reducedends of the semi-cylindrical members. These Vkerfs are iocated opposite each other. 7 andtdes ignate two cap pieces thatare placedon the reduced portion et with the ribs `9 Vand `10 which enter the herfs 5 and 6. The `inner surfaces il `and 12 restupon thereduced surfacet and the annular end surfaces 13 and 14 engage the ends 15 and 160i the semicylindricalmembers 1 and 2. For the purpose ofciamping the members 7 and 8, the ring or collar 17 is provided as shown in Fig. Shaving the set` screws 18 and 19 which engage the outer surface of the members 7 and 8 and force the sameirmlyagainst the two halves of the semifcylindrical .members whereby the same ,are iirmlysecuredon the paper roli. The ribs 9 and 10 which engage the lreifs 5 and serve to drive the roll it Vbeing understood that a shaft ,passes thru the opening 2O of the cylinder7 and the registering: openings of the clamping` members 7 and 8 and the openingl 22 ot the clamping collar or ring.

Itwill, therefore, 'be seen that there is. no danger of the clamping means` working floose on the cylinder, `when the shaft, not shown, is operated.

Referring to Fig. 2, the bristlesZB are securedto the layers of paper 3 by means ofthe staples Qdwhich are located in openings Q5. This is the` usual manner foimattachingthe tuit oit' bristles to a roller.

`Referring to Fig. 6 which 'illustrates a modification of the means of attachingthe bearing` members to" the cylindrical `paper roll, 26 arepins which thru openings 27 in the ends oit"thepaperl tubular member which These rolls are `composed of paper and treated With boiled sulphur to render themV is not made in two pieces, as shown in Figs. l and 8. These pins enter registering openings 28 in the bearing member 29. The reduced portion 3() is the part that rests in the usual bearing boxes, not shown. The roll' shown in Fig. 6 may be employed for conveying the dyes from a suitable vat to a compression or printing roll, not shown.

impervious to the dyes and for retaining their true cylindrical shape which; is not trueof l Wooden cylinders.

VVhatIclaimis: A l. In a comber roll device of the kind described, a cylindrical member formed With an opening therethrough, said member being dividedfinto a plurality of sections, means for securing the members'together, said means comprising sectional cap pieces for engaging the ends of the cylinder, co-operating elements between the cylinder and the caps, and means for forcing the capvmembers tothe cylinder. Y

2. In a comber roll device of the kind described, a cylindrical member formed with an opening therethrough, 'said member being divided into a plurality of sections, means for securing the members together,said means comprising sectional cap pieces for engaging the ends of the cylinder, 4co-operating elements between the cylinder and the caps, and

- means for forcing the cap members to the cylinder, said means comprising a collar provided with set screws Which engage the sections of the cap.

` 3. In a comber roll device nfor the purpose described, a cylindrical member formed with areduced end portion and kerfs in the ends of the reduced portion, caps formed With projections for entering the lrerfs, and ak collar or ring engaging the cap members, and means on the'collar Vfo'r'iorcing the caps iirmly against the cylinder and the ribs into the kerfs.

4. A comber roll device for the purpose dei scribed comprising a cylindrical. member composed of laminationsmeans for attaching a driving element to the" cylindrical memiber comprising a sectional collar formed with projections and the cylinder having kerfs' to receive the projections, a ringengaging the sectional collar, and means on 'thering for forcing the members of the sectional collar toi- Ward each other for clamping the said section to the cylinder.

5. As an article of manufacture a comber roll for combing raw cotton comprising, a tubular member, composed of layers of paper, a bearing member, and meansfor securing the bearing member to the tubular member.
